Redpanda Overview

1. Introduction

Redpanda is a high-performance streaming platform designed to handle event streaming with low latency and high throughput. It is built to be compatible with Kafka clients, allowing seamless integration for existing Kafka users.

Unlike traditional message brokers, Redpanda does not rely on the JVM, which enhances its performance and resource efficiency.

2. Architecture

Redpanda's architecture is designed to be simple and efficient. The core components include:

**Partitioning**: Data is partitioned across multiple nodes, ensuring horizontal scalability.
**Replication**: Each partition is replicated across different nodes to ensure data durability and availability.
**Log Storage**: Redpanda uses a log-structured storage model optimized for fast read and write operations.

3. Key Features

Redpanda provides several key features that make it a compelling choice for distributed streaming:

**Kafka Compatibility**: Works with existing Kafka clients and tools.
**High Throughput**: Capable of handling millions of messages per second.
**Low Latency**: Designed to provide sub-millisecond latency for message delivery.
**Schema Registry**: Built-in schema management for data evolution.
**Easy Deployment**: Simplified installation and management process.

4. Installation

To install Redpanda, follow these steps:

# Using Docker
docker run -d --name redpanda -p 9092:9092 vectorized/redpanda

For a more detailed installation guide, refer to the official documentation.

5. Usage

Here’s a simple example of producing and consuming messages using Redpanda:

from kafka import KafkaProducer, KafkaConsumer

# Create a producer
producer = KafkaProducer(bootstrap_servers='localhost:9092')
producer.send('test-topic', b'Hello Redpanda!')

# Create a consumer
consumer = KafkaConsumer('test-topic', bootstrap_servers='localhost:9092')
for message in consumer:
    print(message.value.decode())

This code snippet demonstrates how to send and receive messages with Redpanda using the Kafka Python client.
